Listen closely. Do you hear it? It's the sound of thousands of teenage girls collectively losing their minds over the internet. That's because last night, HAIM did a live taping for their "You Oughta Know" concert for VH1. And guess who just casually showed up? None other than pop music's newest darling, Lorde, to lend some vocals to a cover of Sheryl Crow's "Strong Enough."

But the real question is: how the hell did this not happen sooner? Lorde and HAIM seem like they would be natural partners in crime. These women are all actively working to change the narrative of women in pop music. They're smart, they're talented, they take creative ownership of their music, they serve as good role models for young women, and they try to keep discussion focused on their work rather than their appearance or their personal lives. Is their music terribly innovative? Not really, but it's incredibly refreshing in the world of VH1.

As for the cover, it's pretty great. HAIM and Lorde exchange vocals on the song, and Lorde's smoky vocals mesh well with HAIM's interjecting chorus. The band pounds out an intricate rhythm on percussion, and there's a nice break with a guitar solo buildup that's appropriately face-melting. But hurry up and watch it for yourself — Viacom has already taken the first video posted of the performance down, so this one is sure to follow. But don't worry, you can always catch the full show on Nov. 21 at 9 pm on VH1.
